Viscometer
A capillary viscometer with a high sensitivity is an ideal complement to the Infrared detector in some polyolefin characterization instruments such as GPC-IR, TREF, CEF or CRYSTEX.
The configuration of Polymer Char’s Viscometer is optimized for each technique to achieve a better performance. The autosampler has a 70 vials’ capacity and consists of two independent temperature zones.
Specifications (Serial 2 capillary configuration)
- Noise: 5 • 10-4 relative viscometer units at 1ml/min solvent flow.*
- Drift: 5 • 10-4 relative viscosity units/hour at 1ml/min solvent flow.*
- Flow path: Serial, after IR detector.
- Viscometer purge valve: Automated and programmable.
- Viscometer electronics: Integrated into the instrument.
